Campbell contributed to
Amiga Power magazine from January 1991, before the magazine launched in April of that year, to May 1994, being promoted to various positions and culminating with deputising as its editor for ten issues between June 1993 and April 1994. Despite regularly professing his love for titles such as
Rainbow Islands and
Sensible Soccer, and compiling "top 100" lists, he is perhaps better known for his unreserved and often highly disparaging critiques. In 1993, he awarded the game
International Rugby Challenge two marks out of a possible hundred, declaring that the
Bosnian War was "Not nearly as bad." Issues 27 to 36 of
Amiga Power have subsequently been cited as belonging to "The Stuart Campbell Era". Campbell remained at the publication until issue 39, which is considered part of "The Jonathan Davies Era" in the chronology of
AP. In 1993, the magazine had to issue an apology during the
Cannon Fodder Controversy after Campbell remarked "Old soldiers? I wish them all dead." A few months later Campbell left
Amiga Power to work at
Sensible Software, the producers of the game. Campbell returned to the pages of
Amiga Power as a freelance contributor during its final few months in 1996, writing several more reviews and features. He also continued to contribute to the online version of
Amiga Power, known as
AP2, which was set up by former writer Jonathan Nash after the magazine's closure in 1996. He wrote for
Teletext's videogame section
Digitiser from 1996 to 2001, as well as its short-lived online successor
Digiworld with
Kieron Gillen, Nash and
Paul Rose, and was Features Editor of the videogames trade magazine
CTW (Computer Trade Weekly) until its closure in 2002. He wrote regular gaming columns for men's magazines including
Esquire,
The Face and
Front throughout the 1990s. He was also a resident gaming expert, alongside former
Amiga Power colleague
Dave Green, on the BBC technology television programme ''Don't Read the Manual'' (presented by Lindsey Fallow and
Rajesh Mirchandani), appearing on most episodes of the show in 2001 and 2002. Campbell's writing has influenced current video games writers, including journalist and
Marvel Comics writer Kieron Gillen.
John Walker also cites Campbell as an influence, calling him a "constant conscience and inspiration". the long-running newsletter
Need to Know said he was "Britain's Best Games Journalist", and
Wired described Campbell as "the UK's foremost authority on computer and video games". Keith Stuart, gaming editor of
The Guardian, said in 2016 that "I would not be doing this job if it weren't for [Amiga Power] – I wanted to write like Stuart." ==Games industry==
